ObjectiveTo implement a model of competency-based education in a basic science competency course using WebCT to improve doctor of pharmacy (PharmD) students' understanding and long-term retention of course materials.MethodsAn anatomy-cell biology course was broken down into 23 modules, and worksheets and mirrored examinations were created for each module. Students were allowed to take the proctored examinations using WebCT as many times as they wanted, with each subsequent test containing a new random subset of questions. Examination scores and the number of attempts required to obtain a passing score were analyzed.ResultsStudent performance improved with the number of times a module examination was taken. Students who initially had low scores achieved final competency levels similar to those of students who initially had high scores. Score on module scores (didactic work) correlated with scores on practical workConclusionsUsing WebCT to implement a model of competency-based education was effective in teaching foundational anatomy and cell biology to pharmacy students and could potentially be applied to other basic science courses.
